In these last few days Israel has taught the world that there is no substitute for ‘boots on the ground’.
IDF chiefs have clearly been taken by surprise at the scale of tunneling that has been going on for the last six years. Nothing less than an entire city underground, they say.
The tunnel entrances are in schools, mosques and private homes. Their exits are just below the surface, ready to be poked open in minutes to disgorge a Hamas column firing RPGs at IDF patrols or dispatch terrorists into southern Israel for murder or hostage-taking.
The tunnels serve a dual purpose: deployment of the terror force and storage of their Iranian rockets and weaponry.
With Kerry back in town and the UN preparing for its umpteenth resolution against the Jewish state, Israel is now not just fighting Hamas but fighting against the clock. Hamas needs a truce to rebuild, regroup and restock for the next round.
We see tunnels being blown and excavated with bulldozers.
But there may be a simpler solution.
Fill all tunnels with gas and light a match.
That will not only destroy the tunnels and weapons caches but blow through to the mosques, houses and other structures deeper inside Gaza which were co-opted into this murderous enterprise.
IDF chiefs may not be ready to do this for fear of collateral civilian casualties.
But these are not places of worship, education or family life.
They are military installations controlled by murderers.
